Fwiw I’ve seen confused or misleading posters reply to this change with statements along the lines of ‘this only means that they don’t allow tourist to apply for greencards in the country’.

Which is nonsense, it applies to all non immigrant visas such as work visas. But it’s a line you’ll see various people try to claim as if this isn’t devastating to every spouse of a us citizen who now can’t get a greencard without leaving their us based job and family.
